The control module 30 is coupled to a light transmitter 20 to drive the light transmitter 20 to light up in a remote control manner. In this preferred embodiment, the light transmitter 20 is a laser transmitter.

The wireless receiver 31 is used for receiving a remote-controlled driving signal transmitted by a wireless manner. The remote-controlled driving signal is sent by a remote control lock or a remote controller of an automobile owner. The controller 32 includes an input terminal coupled to an output terminal of the wireless receiver 31 and an output terminal coupled to the light transmitter 20. The human-body sensor 33 is coupled to the controller 32 for sensing a location wherein the light transmitter 20 cast a light, so to detect whether there is any human or not. In order to avoid harm, if any animal or human is detected in the light-cast location, the human-body sensor 33 notifies the controller 32 to stop the light transmitter 20. Hence the light transmitter 20 does not cast the light. In terms of technique embodiment to implement the human-body sensor 33, the light transmitter is made up by an infrared sensor. Therefore the human-body sensor 33 can detect heat generated by the animal of the human to judge whether the animal or the human stays at the light-cast location.

The practicable example of the preferred embodiment of the present invention of the vehicle locator beacon is clearly described as above. Furthermore, an operation method of the preferred embodiment of the present invention is introduced as follows.

With reference to FIG. 3, the vehicle locator beacon can be mounted in an appropriate position in an automobile. A main principle of mounting for the vehicle locator beacon is to choose the appropriate position for the vehicle locator beacon to cast the light toward an external place of the automobile. In this usage illustration in the diagram, the vehicle locator beacon is fixed at a position 41 above a dashboard in front of a driver's seat to make the light transmitter 20 on the base 10 cast the light above toward a ceiling of a parking lot. If the automobile is parked next to a wall, the light transmitter 20 also can cast the light toward a top of the wall. When the driver returns to the parking lot, the driver can use the remote control lock to send out the driving signal. At this moment, the wireless receiver 31 of the control module 30 receives the remote-controlled driving signal to decode and then send to the controller 32. The controller 32 then drives the light transmitter 20 to generate the light and cast to a location to show a light-spot, so as to guide the driver the find the automobile very quickly. Moreover, the light transmitter 20 also can be mounted with a filter for extending a cast light-spot as a pattern, so as to form a more obvious target to let the drive find the automobile easily.

With reference to FIG. 4, several positions suitable for mounting the vehicle locator beacon are shown. For example, two positions 42 at both headlights of the automobile, a position 41 above a dashboard inside a front windscreen, two positions 43 at both rear-view mirrors of two front seats, a position 44 at a back mirror above the driver, two positions 45 at both taillights of the automobile, and two positions 46 at a top or a bottom of a rear windscreen.

Further, the position 41 above the dashboard inside the front windscreen as described in FIG. 3 also indicates a usage manner of the vehicle locator beacon. The light transmitter 20 casts the lights above, and the light goes through the front windscreen and forms the spot-light or the pattern on the ceiling above the automobile, so that facilitate the driver to find the automobile.
